...alloys were subjected to the pressure tests. They were commercial duraluminum, three aluminum alloys, a lead-calcium alloy, and an iron nitrogen alloy. Each alloy was submitted to the proper temperature, for the time necessary to insure complete solution of the precipitant. It was then quenched in water. The hardness was immediately taken. The alloy was permitted to age at room temperature, one series under high pressures, and a second series at ordinary pressures. After aging for definite time periods, hardness tests were again made...

Last week the Curie-Joliots proposed for elements made artificially radioactive such names as radio-nitrogen, radio-aluminum, radio-silicon. They foresaw the use in cancer therapy of packets of artificial radio-elements, which, because they disintegrate as the radiation dwindles, would not have to be withdrawn from the body after treatment as radium seeds must be. They told of experiments presaging the production of a radio-phosphorus which would emit neutrons (emitted by no natural radioactive substance). And they spoke of work indicating the existence of the neutrino, an ultimate particle lacking electrical charge like the neutron, but small...

Last January the Curie-Joliots of Paris pegged alpha particles (helium nuclei) into boron nuclei and got nitrogen. Similarly magnesium became silicon; alumi-num-phosphorus...

With undying hope in his voice, hollow-eyed young Dr. Robert Cornish last week repeated, over and over, the name of the dog he had killed almost two months ago with ether and nitrogen, revived with chemical and mechanical resuscitants (TIME, May 7 et ante). Lazarus gave no sign that he heard...

Month ago Dr. Robert E. Cornish, jet-haired young University of California researcher, killed two fox terriers with ether and nitrogen, brought them back to life (TIME, March 26). One dog lived a comatose life of eight hours, the other five hours. Last fortnight Dr. Cornish killed a third terrier. For dog No. 3, in addition to the oxygen-saturated saline solution, liver extract, adrenalin, canine blood and rocking board with which he resurrected Nos. 1 & 2, Dr. Cornish had a new help-gum-arabic, to keep the heart from overworking. Revived, the third dog clung to life day after...
